Benefits of technology

[0011]Accordingly, an aspect of the present invention provides methods and apparatuses for enabling secure communication between mobile devices, in which authentication information is exchanged between mobile devices and a secure channel is established by choice of a user, based on an evaluated security level, and further provides computer-readable recording mediums having embodied thereon a program for executing these methods.

[0012]According to an aspect of the present invention, a secure communication method in a communication device is provided. The method includes receiving a first credential of a remote device; receiving first authentication information of the remote device; storing a user record including the first credential and the first authentication information; and evaluating a security level of the received first authentication information.

[0013]According to another aspect of the present invention, a non-transitory computer-readable recording medium having embodied thereon a program for executing a secure communication method is provided. The method includes receiving a first credential of a remote device; receiving first authentication information of the remote device; storing a user record including the first credential and the first authentication information; and evaluating a security level of the received first authentication information.

[0014]According to another aspect of the present invention, a secure communication device is provided The secure communication device includes a credential receiving unit for receiving a first credential of a remote device; an authentication information receiving unit for receiving first authentication information of the remote device; a storing unit storing a user record including the first credential and the first authentication information; and an evaluation unit for evaluating a security level of the received first authentication information.

Problems solved by technology

However, if authentication information is distributed remotely, an attack on the security of the communication channel may occur.
